VT System
Scalable and modular high-performance hardware-in-the-loop (HIL) test bench system
When performing functional testing, the ECU must be tested in a test environment that is consistent with the actual operating environment. When the actual environment is not ready or the cost is too high, in order to thoroughly test the ECU, the R&D team not only needs to connect the communication network to the test system, but also needs to prepare the I/O interfaces required for the system to connect. This task will be performed by the VT System. The VT System integrates all the circuit components required for connecting I/O channels into a single module, such as the I/O channels needed for the ECU output controlling the headlights or the input connecting to the brightness sensor. The ECU's I/O lines are connected to the modular VT System, and when necessary, connected to the original sensors and actuators. A PC with CANoe is connected via an Ethernet-based high-speed real-time network port. This enables the easy construction of flexible test systems without any integration or wiring work, significantly simplifying the setup of test benches and HIL test systems. Using VT System hardware modules and CANoe, vTESTstudio software, users can assemble systems for functional testing of ECUs, vehicle networks, avionics, and industrial control systems. The modular design of the VT System allows for the creation of test solutions ranging from simple test setups to complex test systems:
• Dedicated test systems for each ECU
• General functional test equipment for ECUs and subsystems
• Flexible test hardware for developer workstations

Chassis The VT System offers high scalability. It can be used to build complex, feature-rich test systems: from small auxiliary test tools on developer workstations to comprehensive functional testers and HIL test stations in test laboratories. Since the modules of the VT System are designed to be universal, the test system can be easily adapted to different test objects and test tasks. To meet diverse requirements, the VT System offers a range of solutions, including 9.5-inch desktop enclosures, 19-inch desktop enclosures, 19-inch system enclosures, and HIL custom cabinets.

Back panel
The backplane of the VT System occupies the lower quarter of the chassis height. In the space above, the plug-in modules of the VT System can be accessed directly from the rear. The backplane provides an Ethernet connection for the CANoe PC and a 12V operating voltage for the VT System modules. Each installed VT System module can also be connected to the EtherCat bus via the backplane. Using a second Ethernet connector, multiple VT System racks can be connected to a larger test system.
